Have clear, age-appropriate rules and ramifications for breaking these rules for each child. Each child may need separate rules depending on their age. Ensure each child knows what the rules are. It can be helpful to write them down and post them in a visible place. This can reduce complaints regarding the fairness of the rules when they break them. I have found it helpful to involve each child in setting their rules. This doesn’t mean they make the rules and parents hope they come up with good ones. Parents should direct the rule setting process. If kids are included in the process, they are more likely to be sold on the rules. You may even be surprised with the strict rules some kids come up with. When setting rules, don’t go over the top. More than 10 rules (especially for younger children) may be excessive. Choose your battles.
